There are three primary types of plant oil, differing both the means of extracting the relevant parts of the plant, and in the nature of the resulting oil: Vegetable fats and oils were historically extracted by putting part of the plant under pressure, squeezing out the oil. Macerated oils consist of a base oil to which parts of plants are added.
Dormant oil now refers to the time of application rather than to any characteristic type of oil. Horticultural oils: An oil used to control a pest on plants. Mineral oil: A petroleum-derived oil (as opposed to vegetable oils). Narrow-range oil: A highly refined oil that has a narrow range of distillation. Narrow-range oils fall in the superior ...
The petroleum nut derives its name from the resemblance of the fruit's odor to petroleum-based fuels. The fruits of the tree burn brightly when ignited, and can be used for illumination as torches or candles. [5] Its fruit is also highly suitable for use in producing biofuel. This use has been encouraged by the Philippines Department of ...
Seeds from these plants are noted for their oil content, but little information is available on methods of extracting the oil. In most cases, the plants are grown as food, with dietary use of the oils as a byproduct of using the seeds as food. [45] Bitter gourd oil, from the seeds of Momordica charantia. High in α-Eleostearic acid. Of current ...
To make 180 billion US gallons (680,000,000 m 3) of vegetable oil each year would require 1,150,000 square kilometres (440,000 sq mi) or a square of land 1,070 kilometres (660 mi) on a side. "The gradual move from oil has begun. Over the next 15 to 20 years we may see biofuels providing a full 25 percent of the world's energy needs.
The production process of vegetable oil involves the removal of oil from plant components, typically seeds. This can be done via mechanical extraction using an oil mill or chemical extraction using a solvent. The extracted oil can then be purified and, if required, refined or chemically altered.

Crop oils are composed primarily of paraffin or naphtha-based petroleum oil and crop oil concentrates are composed of emulsifiable petroleum-based oil. [2] The addition of a surfactant and/or emulsifier is commonly added in order to increase spray dispersal and uptake by both plant and insect hosts in pesticides and herbicides.
White oil is an insecticide spray used for controlling a wide range of insect pests in the garden. The spray works by blocking the breathing pores of insects, causing suffocation and death. The spray works by blocking the breathing pores of insects, causing suffocation and death.
